您可能知道，UNIX系统为文件系统上的每一个对象记录一个atime，或称为访问时间，每次读取文件时，atime都会被更新。

As you probably know, UNIX systems record an atime, or access time, for each object on the filesystem that gets updated every time a file is read.

在更新记录之前，我们通过实体对象方法set使用了乐观并发控制。

Before updating the record, we used optimistic concurrency control with the set entity object method.

完整存储库能够转发对象更新，因此它们能传播带有它们自身不支持的属性的记录。

Full repositories are able to forward object updates, so they can propagate records with attributes that they themselves do not support. Executing DIS QCLUSTER (Q1) DEFPRESP CLUSQMGR on QM5 returns.
